What is the purpose of aqueous humor and vitreous humor?
The aqueous humor flows in and out of the front of your eye. Its job is to keep proper ocular pressure (eye pressure) in your eye. The pressure is maintained by having the same amount of fluid come in as the amount of fluid leaving the front of your eye. This fluid fills the anterior and posterior chambers of your eye. The vitreous humor provides nutrients to your eye and helps your eye keep its shape. It sticks to your retina at the back of your eye and lets light in. Your retina is the part of your eye that communicates with your brain so you can see. Forensic scientists sometimes use the vitreous humor to find substances in a deceased body that aren’t expected to be there naturally.
Where are the aqueous humor and vitreous humor located?
Both the aqueous humor and the vitreous humor are parts of your eye.
What are aqueous humor and vitreous humor made of?
Water makes up the majority of both vitreous humor and aqueous humor. Both are about 98% to 99% water. Vitreous humor also contains salts, sugars, proteins and collagen in addition to water. There are also phagocytes, or cells that help keep your eye clean. Along with water, aqueous humor also contains amino acids, electrolytes like sodium and potassium, ascorbic acid, glutathione and immunoglobulins.
What are the common conditions and disorders that affect the aqueous humor or the vitreous humor?
It’s important to have regular eye exams because finding any kind of condition early is best for treatments and outcomes. There are several eye conditions that affect or relate to aqueous and vitreous humors, including: Glaucoma: Glaucoma refers to damage of the optic nerve, which an increased aqueous fluid build-up and high pressure in your eye causes. Glaucoma is the second-leading cause of blindness in the world. Posterior vitreous detachment: As people get older, their vitreous humor gets thinner and eventually loosens from their retinas. When this happens, you may experience flashes and floaters, which may be due to a posterior vitreous detachment. Some people may develop a retinal tear or detachment, so everyone who experiences new flashes and floaters should have their eyes examined. Uveitis: Uveitis refers to a group of diseases that cause red eye, eye pain and inflammation. It can affect your retina, uvea and sclera. The uvea is the part of the eye that contains the ciliary body. The ciliary body is involved in making the aqueous humor. Age-related macular degeneration (AMD): The changes in the vitreous humor as people get older can be a factor in AMD. This condition is the leading cause of vision loss in people older than 50. It affects their macula, the part of the retina that handles central vision. Macular hole: Holes in the macula happen because of trauma or because of another medical condition. It usually only happens in one eye. One treatment is a vitrectomy, which removes the vitreous humor and replaces it with another substance, like a gas. Advertisement
